http://www.oracle.com/technetwork/middleware/soasuite/learnmore/soascheduler-186798.pdf contains a nice example on using Quartz for scheduling of BPEL processes.

wouldnt it be a disadvantage to use a while loop versus using external scheduler like quartz, because a while loop needs to be completely persisted in the db…so even if the scheduling is ‘simple’ it would have a huge overhead over time, and keep filling the orabpel tables?

Thanks Eric. Yes you need a receive or pick to create the instance. I was hoping for a hack or tip to get around this.

Peter,

I think you still need some initial activity to start the proces with (either a receive or pick), after this your bpel-process can be something which runs for ages. But i guess you always need some initial activity to do the first kick-off

Hi Lucas,

I would love to create a BPEL Process Dispatcher process with WHILE-WAIT-INVOKE logic. When I try I get this error: “Initial activity is invalid. An initial activity must be of a receive or pick activity”. How do I get around this?
